the Australian Government has acknowledged that "the aim of the internet provisions in the ACTA is to encourage ISPs to deter copyright piracy over the internet."

But that will not require legislative changes in Australia, the DFAT spokesman said.

...

Under Australia's current laws, there is no requirement for ISPs to monitor the activities of internet users or to supply customer details without a court order."

...

the (Australian) Government is not compelled to sign the (ACTA) treaty should the 27 parties to it reach an agreement.

I note however that apart from that one mention of "internet users" as "customers" above, this pronouncement doesn't otherwise take into account the view of the public at all. Like all other pronouncements on ACTA, it reads as if the public, the ordinary people, are hardly involved at all.

I think authorities the world over will have a big shock when it eventually becomes apparent to them that ordinary people, otherwise know as citizens or as voters or as constituents are in fact involved.
